Durant announced Monday he will sign with the Warriors after nine seasons with the Thunder. Beck reports Durant wanted a more ball-movement oriented offense in Oklahoma City, and was also “frustrated” over recurring issues with Russell Westbrook, who often had the ball over Durant.

“Ultimately he got frustrated and felt that they had plateaued,” a source told Beck about Durant. “[Billy Donovan] came in, and he still had the same issues that he had with Russ under [Scott Brooks]. The offense didn't change much. He still had to take a ton of contested shots every game; and that's when he had the ball at all.”
